# Overview

> An `institution` represents a financial institution like Chase, Wells Fargo, or Mountain America Credit Union.

It's important to point out that many real-world financial institutions will actually have several different `institution` objects within Atrium. This is because, for example, the banking and mortgage divisions of Wells Fargo may use separate online systems for accessing customer data, both of which may be different from the credit card division's system, etc.

  The development environment only allows you to access the top 15 financial institutions.
